The amorphous and crystalline NdFeB films were prepared by RF sputtering at different substrate temperatures.The crystalline specimens,prepared at 600℃ have strong perpendicu- lar anisotropy and high coercivity.And the cystallized alloy from amorphous state also has strong perpendicular anisotripy.

Quantum transport of Au-S-S-Au nanoscale junctions

Applied Physics Letters

Transport in S(2) molecules sandwiched between Au electrodes is investigated with a combination of density functional theory and the non-equilibrium Green's function method. We consider four different configurations and find that their conductances are related to the details of the bonding geometry. When S(2) connects to pyramidal-shaped electrodes at the top site, the transmission is governed by a resonance and is strongly affected by the bias. In contrast, the transport of the remaining three configurations is through several closely spaced broad molecular orbitals, and the transmission coefficient is almost flat around the Fermi level.

The equilibrium of Mg-S in Ni melt was studied by the method of vapour equilibrium in a sealed chamber.At 1530℃ the equilibrium constant of the reaction MgS_(s)=Mg_(Ni)+S_(Ni)and the activity interaction coefficient were determined as K_(MgS)=6.76×10~(-5)and e_S~(Mg)=-9.1.
